Aguila Super Colibri Armmunition has no powder, relying on only the primer to propel the bullet down the bore. The result is an extremely quiet rimfire round, perfect for close-range pest control or quiet plinking.

WARNING:

These rounds are powered by the rimfire primer only.

They must only be fired in handguns.

If fired in rifles, the bullet may remain lodged in the barrel.

Will not cycle the slide of semi-automatic handguns.

Aguila packages these as Long Rifle ammunition, but they are in fact slightly shorter than a 22 Long cartridge.
